Nick ... Hmmm Well looking at Drews recent post I'd say hang on another year The EX camera's with a Nano flash is 50 to 100Mbps with 4:2:2 so its broadcast safe. I don't want to be the man who makes your decisions but I've just been shooting for NHK Europe over the last few days with a polecam (underwater) a Sony Z5 (no nano) and a Sony HDCAM PDW 700 both topside and its all for a HD broadcast programme. So the EX's with nano will be more than enough and as Joe said he was shooting for the Beeb with such a set up.
